I’m a relative Toonboom newbie. Does anyone know why there might be such a substantial lag when I scrub through my timeline? It takes a second or two for the stage to catch up with the cruiser’s position.
And my playback, when I hit the button is about half the speed it is when I export. Why would that be?
Intel HD 4000 built-in graphic GPUs rate as bottom feeders in the GPU hierarchy. Based on your information, you are running a Windows laptop, which may also contribute to additional performance issues. The HD 4000 does not have dedicated video memory, and leeches from your main memory as well. And you are running (it seems) two screens: the built-in laptop screen, as well as the Cintiq.
Well, yes, your system is seriously under-powered for graphics work, I would say. But without additional hardware info (which laptop model, amount of ram,etc.) we cannot say for certain what is causing your lag.
Also, the sound chip in your laptop is probably a low-rated chip as well - it may off-load the playing of sound (partly) to your CPU.
